I used JuliaLang/julia#60478 to find all the `Core.Box` instances in the package and then fix them.

is this assignment needed? (we make sure not to access wrapped_first if extrude is false)

Thanks. It's too bad we need this kind of trick but...
src/dataframe/dataframe.jl
Outdated

Call this len_local like in other places to make it easier to guess why we do this?

I used JuliaLang/julia#60478 to find all the
Core.Boxinstances in the package and then fix them. A variable that gets boxed like this will lose any type information, which can cascade into bad performance and vulnerability to invalidations.The rules are basically that you cannot use a variable in a closure if that variable has been assigned to more than once. Also, using
Base.@lockinstead oflock() doavoids a closure. And if you have a closure that calls itself recursively, it is better to make that a normal function; otherwise, the closure itself will get boxed. Etc...
